Sony's last year Xperia smartphones not getting Jelly Bean update?

Sony’s last year Xperia smartphones won’t get updated to Android 4.1 Jelly Bean.
That’s the logical assumption one can arrive at after Sony UK product
manager John Cooper confirmed that the best model for 2011, the Sony
Xperia arc S won’t get the update. The logic here is that if the
flagship doesn’t get it, inferior models won’t get the update too.

There is no official statement from Sony yet regarding the Jelly Bean
update, but the comments from the Sony UK product manager don’t bring
any good news. So far, Cooper specifically confirmed that the Xperia arc
S and Xperia mini pro won’t be getting the update.

The 2012 models, though, seemingly should get Android 4.1 Jelly Bean.

What’s disappointing here is that while ICS was a huge update requiring a
lot of work from manufacturers, Jelly Bean is generally much lighter
and with less core changes, and subsequently less work required to bring
it to devices. Sony has earlier promised an 18-month support cycle for
its products.
